787 Dreamliner takes to the sky


EVERETT, Wash.--At long, long last, Boeing's 787 Dreamliner is aloft.

On July 8, 2007 (7/8/07), in front of thousands of enthusiastic onlookers, Boeing rolled out the 787 at its mammoth assembly plant here. The aerospace giant promised to change the nature of long-haul flight, making it significantly more efficient than ever before, and promised to showcase the new plane with its first flight just a few months later.

But one delay after another has substantially slowed the 787 program, and even though the plane was brought to the flight line last May, and it was expected that the first flight would take place sometime in the second quarter, that didn't happen. Until Tuesday, when at 10:28 a.m. PST, the maiden voyage of the first Dreamliner finally lifted off from Boeing's Paine Field here, quickly disappearing into a thick cloud cover. The plane is scheduled to land in a few hours at Boeing Field, near Seattle-Tacoma International Airport, about 29 miles south. For Boeing, Tuesday's development is one of its most significant in years. The 787 Dreamliner, which is built from carbon fiber composite materials and has new-style curved wings--allowing it to fly 20 percent more efficiently per passenger than other planes of its size--was meant to be the company's best chance to dominate the next generation of super planes. Originally, said Boeing spokesperson Russ Young, the idea was to build a plane that was 20 percent faster. But eventually, the company decided, after discussions with potential customers, to go for more fuel efficiency.

But the delays--a machinists strike, a problem with the joint between the wing and the fuselage, shortages of parts and supplies, and more--cost Boeing that advantage. And in the interim, archrival Airbus got its much-heralded A380 plane off the ground and into the hands of several carriers. Today, the A380 is flying regularly scheduled service on airlines like Qantas, Emirates, Singapore Airlines, and others.

Still, with the kind of time and money Boeing has invested in the 787, it was hardly going to drop the program because of some delays. Instead, it fought through the problems and continued forward. Last week, the company completed the last tests necessary to get the green light for the first flight, and today, the plane took to the skies in front of a large audience, some of whom were said to have paid $250 for the privilege of watching. Also on hand were thousands of Boeing employees who had front-row seats alongside the runway.

Of course, while all eyes were on today's flight, there is a great deal more work to do before Boeing can deliver its first 787 to a customer--expected to be All Nippon Airways in 2010 assuming no more major delays--or see the plane carry its first paying passengers.

For one, there are six 787s that will be part of the test fleet, with 34 total test pilots. The planes will be put through a battery of in-air stress tests to determine if the model is ready for prime time. All told, said Young, the six already-built 787s will be put through more than 3,000 hours of test flights. In addition, there will be more than 4,000 of ground tests. Young said either the fourth or the fifth 787--in terms assembly order--will be flying tests with a fully fleshed out interior.
